Improve string parsing and JSON parsing (#316)

* Improve string parsing and JSON parsing

- fix JSON parsing of non ASCII string contents
- more precise string parsing errors
- more precise JSON parsing errors
- add `JS_ParseState::buf_start` to compute line/column
- fix HTML comment detection at start of source code
- improve v8 Failure messages (pulled and modified `formatFailureText` from **mjsunit.js**) 
- ignore more v8 tests
